When we think of reds their are so many shades to choose from warm even hot reds true reds! Copper shades all the way through to cool blue Mauve reds.
Reds are the Shade that can be the hardest to get to last keep that rich true colour
Hot or bright roots seems to be a huge problem then we also have to consider a formulation for Grey coverage.
With these examples of Red I have tried to show that it is possible to change shade in this case red without damaging or causing stress on the hair.
The Key to switching colour and shade is to do it in stages working up and down the shades slowly going from lighter to darker is easy tone on tone, to go Darker to lighter the key is to use the pigment you are lifting don’t try for to many levels at once, remember it’s an ever changing journey not a race. using this method you can constantly suggest new change with compromise.
A colour client will stay with you as long as your doing a great job so take your time explain what’s possible both short term and long ! have fun.
But consider the environment you are working in the history of of previous colour application. consider and plan colour goals for coming months so change is possible with out over processing and or a poor job!
